Notes: 1. Package power includes both MCP components: processor and PCH.

2. Measured at Tj = 35 °C.
3. The C7 power is measured with LLC ON.
4. The C10 power is measured with LAN disabled.

Occasionally the processor may operate in conditions that are near to its maximum

operating temperature. This can be due to internal overheating or overheating within

the platform. To protect the processor and the platform from thermal failure, several

thermal management features exist to reduce package power consumption and

thereby temperature in order to remain within normal operating limits. Furthermore,

the processor supports several methods to reduce memory power.

The purpose of the Adaptive Thermal Monitor is to reduce processor core power

consumption and temperature until it operates at or below its maximum operating

temperature. Processor core power reduction is achieved by:
•

Adjusting the operating frequency (using the core ratio multiplier) and voltage.

•

Modulating (starting and stopping) the internal processor core clocks (duty cycle).

The Adaptive Thermal Monitor can be activated when the package temperature,

monitored by any digital thermal sensor (DTS) meets or exceeds its maximum

operating temperature. The maximum operating temperature implies either maximum

junction temperature Tj

MAX

, or Tj

MAX

 minus TCC Activation offset.

Exceeding the maximum operating temperature activates the thermal control circuit

(TCC), if enabled. When activated the thermal control circuit (TCC) causes both the

processor core and graphics core to reduce frequency and voltage adaptively. The

Adaptive Thermal Monitor will remain active as long as the package temperature

exceeds its specified limit. Therefore, the Adaptive Thermal Monitor will continue to

reduce the package frequency and voltage until the TCC is de-activated.

Tj

MAX

 is factory calibrated and is not user configurable. The default value is software

visible in the TEMPERATURE_TARGET (0x1A2) MSR, bits [23:16]. The

TEMPERATURE_TARGET value stays the same when TCC Activation offset is enabled.
